Frequently Asked Questions

TRC accepts orders placed via our website, email or phone. To place an order, we require a purchase order, which includes a purchase order number (if applicable), shipping and billing addresses and method of shipment preferred. Credit card orders are also accepted.

Product availability information is provided on individual product pages. Although we make every effort to ensure a continuous supply of our products, occasional circumstances may force us to discontinue or temporarily run out of a product. If you note on our website, we list the Inventory Status for each product.
These include:

In Stock: At the minimum, the smallest package size is available for purchase.

You can set up an account by placing a website order and completing the associated fields. You may also contact us by email with information about your company/organization such as website, company size, company history, etc.

Until recently, most products have been assigned a purity that is estimated based on 1H NMR, TLC and Elemental Analysis (+/- 2%). Our purities are given on a dry basis and do not include trace water or solvent. For purity of an individual product please consult the batch-specific certificate of analysis (CofA). This being said, some products are not suitable for HPLC testing.

Our purities are not considered quantitative. For customers who wish to know the potency of our products, additional testing can be ordered, i.e. TGA, Karl Fischer, which will allow the customer to calculate the potency value. TRC does not list potency on product Certificate of Analysis (COfA).

TRC is currently not certified by any external regulatory authority (ISO, GMP/GLP, FDA or otherwise) and/or independent third parties. However, our subsidiary, Synfine Research Ltd., is routinely inspected and is ISO 9001 certified. If requested, TRC can provide ISO certified products through our subsidiary, Synfine Research Ltd.

All of our products are provided with the highest level of spectral documentation. But, since TRC has not yet achieved any ISO certifications or GMP/GLP manufacturing, we cannot claim that our products are certified reference standards. Our products are not qualified against any primary standards. We use NMR, Mass Spectrometry and Elemental Analysis to confirm identity. Product purity is based on HPLC or NMR, TLC, and Elemental Analysis.

Currently we do not perform stability testing on our products. Retest dates are assigned to products based on what is known from the literature and from our chemists’ experience/observations while working with the product during synthesis and analysis. Retest dates of 1, 4, 7, and 10 years are given to products accordingly. Our most sensitive products have a retest date of 1 year and will be tested by 1H NMR prior to shipping. Products that have longer approval periods are less sensitive and more stable. All products that are expected to be sold are tested 1 year before their retest date, with the exception of sensitive materials, which have 1 year retest dates and are tested 6 months prior to expiry.

Products which have a long term recommended storage temperature of 2 to 8°C and -10 to -20°C are normally shipped at ambient temperature as they are stable at room temperature for short periods of time (approx. 2 weeks of transportation), unless otherwise specified. This is based on what our chemists observe while working with these products. Lower temperatures are typically assigned for long-term storage in order to maximize shelf life. Products that are unstable and/or have a recommended storage temperature of -86°C are shipped on dry ice in order to preserve product quality.

The chemical purity of technical grade products is estimated to be between 35 to 70%. Reasons why a product may be assigned technical grade include: lack of stability, purity unquantifiable based on the analysis performed, or difficult purification process.

For normal packages, we weigh out a surplus of product that could contain 10% or more excess material, e.g. for a 1mg order you can expect approx. 1.1 to 1.2mg of product. This is so that sufficient material will be provided with your order. If an order includes our exact weight service, we will still provide a slight surplus of material, however we will weigh your order on a microbalance and provide you with the exact quantity received up to 3 decimal places.
